Is it acceptable to omit the last period of an acronym?

Solution 1:

I have never seen such a usage. I think it was a misapprehension made by the OP of that particular question.

Solution 2:

If you are writing in a style which uses periods after each letter in an acronym, you can skip the last period in the acronym if the acronym is the last word in the sentence, in which case the sentence-final period, exclamation point, or question mark will replace it.

I have never heard of A.V.C.

I can't believe you work for I.B.M!

Is this the way all astronauts are treated by N.A.S.A?

Solution 3:

I've pondered this issue myself, ever since seeing the usage in N.W.A (Niggaz Wit Attitudes).

It is the first usage that I am aware of and believe it has been the inspiration for further usage in the Black community. Sort of like a FUBU writing style.
